VII. Specific Model Data

Mounting

The Kooltronic Special Purpose Air Conditioners K_NA4C3P21R have been engineered to be installed easily. These units utilize double layer gaskets. The first gasket layer is placed on the outside perimeter of the front panel that is sealed against the customer enclosure. The second layer is placed on the two cutouts in the front panel. The first gasket layer will allow a small amount of water between the two layers. The second gasket layer totally protects an enclosure from ambient air, rain or hose down water. This gasket arrangement assures the integrity of the closed loop system and is necessary to maintain the NEMA 4 rating.

Prior to mounting, refer to page 8 for the general arrangement drawing showing dimensions and locations of mounting holes and cutouts. Prior to cutting or drilling, make sure that cutouts and mounting holes do not interfere with components inside the cabinet. To avoid damaging your air conditioner, please read the following information before installation:

1.It is recommended that a lift truck be used for installation.

2.Attach the Mounting Plate to the enclosure using (3) 1/4-inch stainless steel nuts, (3) sealing washers as a spacer and (3) 1/4-inch stainless steel mounting nuts. Sealing washers must be placed against customer enclosure (see mounting drawing).

3.Place the air conditioner on the lift truck. Insert a 1-inch (approximate) wooden block between the lift truck bottom and the air conditioner bottom so that the angle between the unit mounting panel and the air conditioner is about 15 degrees.

4.Adjust the lift truck height so that the air conditioner hook is located approximately 1/2-inch above the mounting plate.

5.Route the power cord through the discharge (upper) air cutout.

6.Move the air conditioner toward the enclosure panel so that the gap between the hook and the enclosure is about .05-inch.

7.Slowly move the lift truck down until the hook engages with the mounting plate. Continue to lower the lift truck. The air conditioner will hang from the mounting plate flush against the mounting panel.

8.Insert stainless steel screws through the holes in the mounting plate bottom flange and the enclosure panel. Install sealing washers and stainless steel nuts on each screw from inside the enclosure and tighten (see mounting drawing).

support the additional weight of the air conditioner. Also be certain that when the door is opened fully, the cabinet does not become unbalanced. The actual weight of the unit can be found in the performance specifications.
